Note:
1. This test usesan attenuated radiation method for the reading of FAU (Formazin
Attenuation Units). The results can not be used for USEPAreporting purposes, but may
be used for routine measurements.The attenuated radiation method is different from
the Nephelometric method.
2. The estimated detection limit is 20 FAU.
3. Collect water samplesin clean plastic or glass bottles and analyse the water sample
as soon as possible. It is possible to store the sample at 4°C for 48 hours. Before
measurement warm up the sample to the temperature at collection time. Temperature
differences between measurement and sample collection can effect the turbidity of the
sample.
4. Colour interferes if light is absorbed at 530 nm. For strong coloured water samplesa
filtrated portion of the sample can be used for zeroing instead of the deionised water.
5. Air bubbles interfere and can be removed using an ultrasonic bath.
